赞一个先。 请问对于2-3GB的实例，数据频繁修改与读取，在compaction期间出现概率性的性能大幅抖动（70%下降），这块优化上，有没有建议呢？

25 禁用 WAL 时，DB::Flush() 只对单个 Column Family 的数据固化操作是原子的，对多个 Column Family 的数据操作则不是原子的，官方考虑将来会支持这个 feature；

请问这个出处是？

找到了，不过他们仍然没有是实现这个功能。

既然找到了，就把rocksdb的官方内容和连接贴过来呗，多谢。

Q: I disabled write-ahead-log and rely on DB::Flush() to persist the data. It works well for single family. Can I do the same if I have multiple column families?

A: No, currently DB::Flush() is not atomic across multiple column families. We do have a plan to support that in the future.

我一年产量也不足十篇，没必要 RSS 了。或者你加我微信好友【微信号在博客里】，关注我朋友圈也好。
